In elm you'd do one of two things: keep all the arguments on one line, or put each on its own line. At least, according to the formatter's opinion (which is honestly so nice to use when it just snaps everything into place every time you hit cmd-s). Of course, this convention is violated all the time when listing all the public exports of a package (with good reason IMHO; it lets your group similar things onto lines together) so it's not much of a convention: https://github.com/rundis/elm-bootstrap/commit/e412efe628854...
